If you’ve been tuning in to this season of CBS’ ‘Big Brother,’ or you're a big Ariana Grande fan — or both — then you know the pop star’s older brother Frankie has become his own celebrity on the popular reality show. On Thursday, Aug. 8, Ariana popped by the live filming of the show to support her favorite cast member.

Host Julie Chen grabbed a selfie with the singer, and posted it to Instagram with the caption, “Look who is in the live audience tonight cheering on her big brother ON #bigbrother! @ArianaGrande #BB16.”

Us Weekly reported that the 21-year-old was present for the live show in case Frankie was booted from the game during that episode’s double eviction. He’s stressed a few times on the show how close he is with his sibling, so it would be a nice surprise to have Ariana help alleviate the sting of eviction.

Spoilers ahead!

Luckily, Frankie managed to keep his spot in the house this week, but the competition is getting fierce as the weeks go by. Will the ‘Problem’ star make another appearance at next week’s live show? Keep us updated, Julie!
